Báo cáo khoa học: Transcriptional responses to glucose at different glycolytic rates in Saccharomyces cerevisiae ppt

... expression at high glycolytic rates, but sti- mulated SUC2 expression at low glycolytic rates. This suggests that Mig1-mediated repression can be overruled by factors mediating induction via a low glucose ... concentration of glucose, while the level of phosphorylated Snf1 was increased in cells shifted to a low concentration of glucose. In the HXT-null strain, Mig1 migrat...

... or spherical [1]. Although intriguing, this observation points to the existence of additional factors in filamen- tous fungi that contribute to the formation of mature and functional Woronin bodies. Although ... cells lacking Vps1p and Dnm1p, dynamin-like proteins required for the division of peroxisomes, the Woronin-body-like organelles remained attached to peroxisomes. The data indic...

... used to model the P-selectin-binding domain of the mucin-like glycoprotein PSGL-1 [73,74]. This ligand is involved in the initial homing of leuko- cytes to sites of in ammation [73,74]. The binding ... chronic in ammation in mammalian brain tissue both in vitro and in vivo, including in the detection of cerebral malaria. Retooling of this reporter system also allowed sys- tema...

To allow for these other relations, a function was added to the web page allowing the annotator to enter the appropriate relati...
